Use type-1 DV with VirtualDub / Avisynth

[uttam]

Hi!

I have read at a lot of places that it is not possible to use type-1 DV AVI file with Virtualdub. I have been able to use type-1 DV AVI in Virtualdub using following Avisynth script:

------------
fil = "<dv1_file>.avi" # replace with your type-1 dv filename.
vid = avisource(fil) # video using VFW
aud = directshowsource(fil) # audio using DirectShow
audiodub(vid,aud) # combine audio and video and frame serve 8)
-----------------

I am also using dvinfo filter (in avisynth) to print the recording time/date on the video and then use Virtualdub to save it as divx/xvid and mp3/ogg format.

I am posting it here so that other members can also try this technique and let me have comments.

Kind Regards,

The latest version of Virtualdub (1.6) accepts Type-1 directly.

thanx gadgetguy!

I downloaded latest Virtualdub, it does opens the type-1 dv file but plays/encodes only left channel of the audio. Any remedy for that?

Thanks and Regards,

I haven't experienced that. All of my videos have had both audio channels, no problem. Sure it's not a hardware problem?

[uttam]

No, it's not a hardware problem. It happens only when i open the type-1 dv file directly in Virtualdub. Other files work fine. The file information window shows that the audio is 2 channel PCM but i hear only left channel when playing. Could it be a codec related problem?

That's possible, but since I can't duplicate the problem you're having, I can't be sure. If you extract the audio to a wav file is there only one channel? (Set audio to direct stream copy.) Can you hear both channels in the avi if you play it in a player like Media Player Classic?
